The product is therefore to be recommended absolutely. I myself was a bit skeptical as well keeps the whole but considers it.
However important the correct preparation. Rims very thorough clean, lint-free as possible get (alcohol) and then evenly in several layers aufsprüchen. (Only if the rim is clean, the film can also stick it anywhere)
I have to the can moved smoothly from left to right while I circled repeatedly around the rim. Of course in both directions. While holding relatively large distance, so that the rim rather "fogged" as is sprayed. This achieves a uniform appearance. Between the layers let dry. (Hold individual layers very thin, otherwise in the corners quickly make noses) I have applied 4 layers and 3.5 doses for four 16-inch wheels required. Takes incl. Wheel cleaning about 5h.
Moreover, it seems so as if dirt sogut liable as at all. After each rain, the rims are clean. (I tested with a finger, as you can see black brake dust on poor black rims yes)
CONCLUSION: Super optics, last forever but who works once thoroughly has later also last a lifetime
